Heat butter or margarine in skillet. Add onion, green pepper, and Redi-Base. Sauté one minute. Add ham, black and red beans, mustard, and black pepper. Sauté until heated thoroughly. Divide between the pita pockets and add a little western style dressing for that extra kick.
Food for Thought
Other ideas for leftover diced ham: Add to scalloped potatoes, to a rice pilaf, to soups like a Corn Chowder or a Navy Bean Soup.
